Question

the sides of a triangle are in the ratio 1 ratio 3 ratio 5 and its perimeter is 90 cm the length of its largest side is ​

Answer 1

Answer:

50 cm

Step-by-step explanation:

The lengths of the sides of the triangle = 1x:3x:5x

perimeter = sum of all sides

90 = x + 3x + 5x

90 = 9x

x = 10cm

length of longest sides = 5x

                                       = 5 * 10

                                       = 50 cm
